摘要
设计了一研究型综合化学实验,主要介绍了一种纳米二氧化锰粉末电极的制备工艺,并通过组装成三电极体系进行恒电流充放电测试,从而计算纳米二氧化锰研究电极的比电容。在实验教学过程中引入前沿热点超级电容器,可以让学生更加直观地了解化学电源的基本结构与性能评价标准,拓展他们的知识领域。
A research-oriented comprehensive chemical experiment was designed.The experiment mainly introduces a method for the preparation of nanostructured MnO2 electrodes.By assembling a three-electrode system,the constant cur-rent charge/discharge tests were carried out to calculate the specific capacitance of the nano-MnO2 electrodes.Introdu-cing the focus on supercapacitor in experimental teaching,it will make students know more about the basic structure and the performance standard of power sources directly,and...
